This set of 5 Tree Stake Lights is 43cm high and has 1 static green LED per stake with a 50cm clear lead cable. They use our patented NOMA Fit and Forget battery technology. The inbuilt timer is set to 6 hours on and 18 hours off; saving your battery power and ensuring the lights work for at least 60 days in static mode with a timer or 72 days in flashing mode with a timer without changing the batteries. There are 8 multi-function settings. The easy-access battery box means there is no screwdriver required as well as being weatherproof so the light chain can be used both indoors and outdoor. These stake lights will light up any corner of your garden as the LED light creates a nice glow against the Christmas Tree shape. 3x AA Alkaline batteries are required.
